llseek(3)                  Library Functions Manual                  llseek(3)

NAME
       llseek - reposition read/write file offset

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       [[deprecated]] loff_t llseek(int fd, loff_t offset, int whence);

DESCRIPTION
       This is not the function you are interested in.  Look at _llseek(2) or
       lseek(2).

HISTORY
       When users complained about data loss caused by a miscompilation of
       e2fsck(8), glibc 2.1.3 added the link-time warning

           "the `llseek' function may be dangerous; use `lseek64' instead."

       Since glibc 2.28, this function symbol is no longer available to newly
       linked applications.

SEE ALSO
       _llseek(2), lseek(2), lseek64(3)
